Definitions
- the present invention pertains to an internal combustion engine comprising a drive connection for auxiliary equipment including a step-down gear and wherein a pump impeller of a coolant pump and a pump wheel of a lubricating oil gear pump are situated on a common shaft.
- An object of the present invention is to provide an internal combustion engine comprising a drive connection of the aforementioned type with an auxiliary piece of equipment wherein the drive connection for a lubricating oil gear pump and the coolant pump is compact, simple and inexpensive, while retaining a gear reduction for the coolant pump.
- an internal combustion engine comprising a drive connection with auxiliary equipment which includes a step-down gear and wherein a pump impeller of a coolant pump and a pump wheel of a lubricating oil gear pump are situated on a common shaft with the pump wheels of the lubricating oil gear pump forming the step-down gear for the coolant pump.
- auxiliary equipment which includes a step-down gear and wherein a pump impeller of a coolant pump and a pump wheel of a lubricating oil gear pump are situated on a common shaft with the pump wheels of the lubricating oil gear pump forming the step-down gear for the coolant pump.
- the drive connection further comprises a secondary drive shaft driven by the crankshaft of the engine, and wherein the pump wheels forming the step-down gear include a drive pump wheel of the lubricating oil gear pump which is situated coaxially to the secondary drive shaft and is connected to the secondary drive shaft by male coupling means.
- a pump unit which can be preassembled and which can easily be attached to and detached from the housing of an internal combustion engine.
- the invention is further characterized in that the lubricating oil gear pump and the coolant pump are located in a common pump housing at a face of a housing of the internal combustion engine, and in that the pump wheels of the lubricating oil gear pump are recessed in the pump housing such that the faces of the pump wheels face towards the housing of the internal combustion engine.
- a mounting pad of the pump housing and a flange facing of the engine housing lie in the same plane. This simplifies the arrangement of the flange facings at the housing of the internal combustion engine and pump housing.
- An additional feature of the disclosed embodiment of the invention is that an inlet chamber of the coolant pump is situated in the pump housing between the lubricating oil gear pump and the impeller of the coolant pump. This takes advantage of the construction space acquired by the axial room needed by the coolant pump seal to ensure a compact arrangement of the inlet chamber of the coolant pump.
- the drawing shows a vertical longitudinal section of a lubricating oil gear pump and a coolant pump, including its drive connection to a secondary shaft of an internal combustion engine according to one embodiment of the invention.
- a pump housing 72 with its mounting pad 73 is attached to a flange facing 71 of a housing part 6' of an internal combustion engine, the rest of which is not shown.
- pump housing 72 In its section facing housing part 6', pump housing 72 has pump wheels 59' and 60' of a lubricating oil gear pump in a recess 74, and in the section opposite that it has a coolant pump 22' with an impeller 58'.
- Housing cover 75 forms the closure housing 72.
- Drive pump wheel 59' of the lubricating oil gear pump features a smaller number of teeth than does driven pump wheel 60'.
- pump wheels 59' and 60' form a step-down gear for coolant pump 22'.
- the drive pump wheel 59' is secured on a shaft 76 mounted in pump housing 72 in such a way as to resist torsion.
- Shaft 76 is arranged coaxially with a secondary drive shaft 51' of the internal combustion engine and is connected to secondary drive shaft 51' by means of a male coupling 77.
- the pump wheels 59' and 60' of the lubricating oil gear pump are recessed in the recess 74 of the pump housing 72 such that the faces of the pump wheels face towards the housing part 6' of the internal combustion engine.
- the mounting pad 73 of the pump housing and the flange facing 71 of the engine housing lie in the same plane. This simplifies the arrangement of the flange facings at the housing of the internal combustion engine and pump housing.
- An inlet chamber 82 of the coolant pump 22' is situated in the pump housing 72 between the lubricating oil gear pump, particularly the pump wheels 59' and 60' thereof, and the impeller 58' of the coolant pump. This takes advantage of the construction space acquired by the axial room needed by the coolant pump seal to ensure a compact arrangement of the inlet chamber of the coolant pump.
- the driven pump wheel 60' of the lubricating oil gear pump and the impeller 58' of the coolant pump 22' are mounted on a common pump shaft 56'.
- the pump shaft 56' is journalled in the pump housing 72 and in the housing part 6'.
- a first sealing 78, a ring chamber 79 and a second sealing 80 are arranged between the pump wheel 60' and the impeller 58'.
- a channel 81 leads from the ring chamber 79 to the atmosphere.
- a substantially annular inlet chamber 82 of the coolant pump 22' is arranged at a distance around the sealings 78 and 80 and the ring chamber 79, whereby the axial dimension of the inlet chamber 82 decreases helically.
- the lubricating oil gear pump and the cooling pump 22' can be preassembled as a common pump unit. In this way the assembling with the housing part 6' is simplified.
- the inlet chamber 82 of the cooling pump 22' is situated space savingly between the pump wheel 60' of the lubricating oil gear pump and the impeller 58' of the cooling pump 22'. This takes advantage of the radially outer part of the interspace between the pump wheel 68 and the impeller 58' which has to be provided for the sealings 78 and 80 and the ring chamber 79.
- the compact structure of the internal combustion engine is very much improved by means of this compact arrangement of the pump unit consisting of the lubricating oil gear pump and the coolant pump 22' and by using the pump wheels 59' and 60' of the lubricating oil gear pump as a step-down gear.
